Product Overview

The 303-1AH-C-R1-U01-12VDC is a genuine Song Chuan automotive relay designed for electrical switching applications in cars and trucks. It uses a 12 VDC coil to operate a single-pole, single-throw normally open contact.

Product Features

The 303-1AH-C-R1-U01-12VDC automotive relay is manufactured to Song Chuan factory specifications for electrically controlled load switching.

  • Uses a low-current control signal to operate the switching contacts that carry current to the connected electrical load.
  • Separates the control circuit from the switched power circuit, allowing each circuit to perform its corresponding electrical function.
  • Routes load current through the relay contacts rather than through the control switch or electronic control unit output.
  • Provides a normally open contact path that closes when the relay coil is energized to activate the connected circuit.
  • Connects to the electrical system through metal pin terminals located at the bottom of the relay.
  • Reduces arcing at the control switch by transferring the load-switching function to the relay’s internal contacts.
